What is the easiest way to implement a membership system technology wise for my social networking company?

The best technology is whatever gets you up and running the quickest. You'll throw away the first iteration (and possibly the second and third...) anyway. What you need most in the beginning is to test your idea and get feedback, and you need it fast.

I would suggest the first question to ask is "what problem do I solve?" And of those people I solve problems for "who do I create the most value for?" In the non-profit world you need to add "How does my business help the non-profit run better and/or help the group the non-profit focuses on?" For example, if you've created a platform that drives donations, your company "has created a platform that helps you reach fundraising goals faster." What you don't want to do is market and sell to B2B and B2C audiences simultaneously. They have different ways of buying - a B2B audience needs to have their benefits quantified (using your thing makes me x amount more) - and it's extremely hard for a startup to be able to do both well. Better to start with one, execute really well and move into the other. Feel free to give me a call and we can dig into who your most valuable audience is.

Yes absolutely. Depending on the needs of your service and database traffic, some chains are better than others to use. Steemit.com is a good example of blockchain, curation, filtering by users, with a built-in economy.

If you and this person, *know* they won't be the CTO, then absolutely not. If there's an understanding that the engineer you are working with is going to "cap out" soon beyond the MVP, why would you ruin your cap table? This *should* help you get a reasonable amount of equity. http://foundrs.com/ The most crucial question is where this current contributor is likely going to be out of their element. Are they only front-end and have no back-end ability? If so, you really should raise (from a friend or family member) or borrow the money necessary to pay this person a reasonable cash rate. If on the other hand, they can take a successful MVP and build a reasonable back-end but will cap out on scaling it past 100,000 users, or for example, you're an enterprise company and you know you'll require a technical person to be part of closing early sales, then it's ok to give up meaningful equity. But another key question is: Are you ok to let this person define your company's engineering culture? If this person isn't capable of or comfortable managing your tech team in the early-days, this person should have no more than 10% equity. Of course, your shares and theirs (whatever you decide) should be subject to a vesting agreement (minimum 3 years and preferably 4). It's easy to give away equity when it's worth very little but as I've said here before on Clarity, imagine your company today being worth $100,000,000. Can you imagine this person contributing $20,000,000 worth of value to achieve that outcome? $30m? $50m? Here's the thing though. If this person can grow into a CTO, and wants the chance, and there's no warning signs that it will be a tough slog for them to get there, and they're a passionate believer in what's been built to date, then it's entirely reasonable to bet (with equity) that they can get there. I know a lot of CTO's of great Series A and beyond companies with amazing traction that started off as lacking a lot of the criteria of a great CTO candidate. This is an area I've helped coach a lot of startup CEOs through and have experience in myself. Happy to talk through in a call to understand the specifics of your scenario and provide more detailed advice.

One of the best and most popular script used is Vbulletin. Most of the reputable forums are powered by Vbulletin. The second recommendation I'd have is phpBB. It is absolutely free and open sourced versus Vbulletin which is licence based. I have used both and had no problems with either of them. If you can fork out some money I'd suggest going with Vbulletin. Here is a list of the biggest internet forums http://en.wikipedia.org/wiki/List_of_Internet_forums. You can see most of them are powered by Vbulletin and the second most popular script is phpBB. Regarding fresh look you can simply hire someone or buy a Template.
