Welcome, Blue Badger, to the Ironhide forums! I hope you'll enjoy your stay as well.
The only tip right now is to sit tight and wait, as forum activity hasn't been too bustling as of late. However, the Iron Marines beta is coming out very soon, in addition to the game itself coming sometime this year, so there will be plenty of conversations and discussion to participate in when that happens.
During the wait, feel free to browse through any past topics and see what we've been talking about, whether it was about Kingdom Rush or anything else (the latter is in the Off-Topic thread, where there is a slaughter thread starting- you can read the discussion to understand what a slaughter thread is). And of course, feel free to ask me or anyone else questions!
