I think sponsors will be easier to get once your group becomes more active in the forums and activities such as the LAN parties. Most sponsors will get an idea of how active a group is by trolling visiting the website site and looking thru your forums.
Interestingly enough, I posting something almost verbatim to this in the exec section a month ago 
The current management feels that a Facebook group is enough of a web presence and has shifted much of their efforts there rather than here. Maybe now that some professionals are weighing in with opinions similar to ours we can change that.
