I personally am always happy to share tips - more so especially because I'm not currently running a forum, and don't have plans to run one in the immediate near future, so I don't worry about competition or anything like that! (not that I worried overly about it before either
)
Ultimately, being a good admin is about the effort you put in. I'm always happy to share tips with people from my own previous success (although as I've said previously, I've had one big success and several failures, so my tips might not necessarily be "pro tips"!), but at the end of the day, tips and tricks will only get you so far. The ultimate measure of the success of your community will be primarily affected by the time & effort you're willing to dedicate to your forum as an admin.
