I joined in January, but really became active about 3 months ago. I'm good with vomment memes, but there's others that are even better. It's great when we get a good reply war going where two or more people try to top each other. A lot of my comments and replies will be submitted to see if they can be featured. This is what I would call a standalone worth submitting.
Best thing I can advise is make memes and make comments. Comments give you a lot of points. I'm pretty sure that's what the lion's share of mine are.
There's a lot of cool people here, and the number of jerks is pretty low. Yeah, can't have a public forum without them coming along.
Anyway, welcome to imgflip. Enjoy your stay and most important: have fun.
