Making a page to try and get donations is a bit... meh. The jumping community is pretty small really, and it's only very recently I have seen a donations link on TF2RJWeekly - for TF2 items to be used primarily for competitions. It's not a big problem, because no-one is likely to donate. But you have to understand something like that wont sit well with with some people (even if it's just a punt).
But as I don't really care about that, I'll say the following:
1. What hidden talent are you hoping to showcase that wouldn't be better revealed by posting on these forums and submitting to TF2RJweekly? People who are good, but not as good as some of the veterans here (and could get looked over)? Or simply people you happen to know?
2. Why does your group identify as RocketJump_ (with an underscore at the end)? Are you hoping to capitalize on the fact that it bears resemblance to STAR_ who has a very popular channel?
3. Did you read this through after you wrote it?
TF2 Jumping Tips for New Jumpers. Almost all of the information is badly informed, and some parts are just plain wrong. Fire your rocket just after you land to do a speedshot? I think you mean just before... Or maybe even
quite a bit before. Some of these techniques can be confusing as hell to a beginner, the last thing you want to do is be telling them to do it the wrong way!
