Guess I'll say welcome to the crazy train.
A couple suggestions for you:
1) Don't rush to get Members+. Just post when you have a thought, and don't worry. With only a couple posts each day the coins will add up, and there are good games and discussions to find in the open area.
2) Put your coins in the bank. Collect the interest every day, and you WILL get enough coins over time.
3) When you get enough coins to buy Member's+ WAIT. If you wait a couple days before buying you can collect extra coins to make the journey to the higher cost prestige levels go a little faster. The more coins you have in the bank the more you get from interest. So, keep posting a bit and wait 2-3 days for the extra boost if you want the nifty extras from the prestige levels.
4) Whatever you think, remember that Pineapple on pizza is BAD.

That seems to be one of the most active threads.
5) Other threads of interest may be: What is the right number of ladies in Harem games, Star Trek v Star Wars, and many others.
Hope that helps.
