I haven’t yet made a donation, but I will....promise
However, I’ll make this suggestion.
On another BBS I subscribe to, they have the option of becoming a paid subscriber. You can sign up for 1yr, 3 yr, life. Now their "default" / open to the public BBS, has Ad’s for the passer-by. When you subscribe, the Ad’s are removed via a script, when you login. Additionally, your profile on the left of a post will include a footer saying something like "Life Subscriber"...Basically indicating that you donated to the cause.
Now I am not advocating that you start running Ad’s on the site. However, it might be a nice touch when someone does donate, that he or she has the option of including a footer.
just a thought
to see what I am refering to, search for user id "24jedi"
