I can't be the only one here that wants to see this users site.

Even better, invite real life friends that are into the forum subject and have them post. When we first started the site it already had 7 active members : Wife, 2 of my friends, and 3 of hers

You also forgot to mention a good reliable host, it's really frustrating using a forum that has 80% uptime rest was all internal server errors or down time. Whenever you post you are forced to copy paste your message onto notepad just in case it times out when trying to submit the message...

Well I make posts about contests, the site, the forum, as well as general re-blogs of photos/videos that are related to the site / what the site's about! :-)

My girlfriend loves Tumblr, so she decided to make one for our website. Just like you mentioned she does all the above ^^
Although it's doesn't get a lot of Tumblr users to the forum, it's better then nothing (:
Not to mention it's pretty easy to find people that have similar interests on Tumblr. Thanks to the Tagging system.
