Working the way I do and the amount I do, I don't have time to contribute as much as I would like. I spend literally my entire lunch break, as well as a few hours a night (when not on call or on special projects for work) on the site. I would love to contribute something to the site.
Honestly, the 'benefits' do not really entice me. I guess simply because I enjoy doing what I can to help (granted, most of my stuff is unnoticed, but what can ya do? hehe). I do not expect to be a part of a VIP forum for those that are able to contribute more time than I. Its more for the warm fuzzy feeling of knowing I am helping in the best way I can for the moment.
Now, once I have my surgery and I am down for a month, hibby and Diesel better watch out. Will have nothing to do but take pain meds and sit in front of the computer.
Seriously though, I will happily donate if things are becoming a strain.
