I personally never ask people to donate. Money is just such a sensitive subject, and way to personal, imo. I don't fault anyone for donating or not. IMO, asking someone to pay for "the Internet" just goes against everything the Internet was originally meant to be, that is, "free" communication and "free" distribution of information.
And with money being such a sensitive issue, I can understand how even a little polite nudging might come across as offensive, ESPECIALLY from a non-admin of the site. Seriously speaking, if I just joined a forum and some random other forum user asked me to cough up money, I would probably be taken aback a little. Maybe after a year or two of heavy use, then if someone asked me to consider donating, I would be OK with it, but not so early on. I didn't pony up for quite a while. I was a non-paying user for at least a year, iirc, maybe more.
I donate because I love this site and it is a great place to learn about the VehiCROSS and talk with fellow enthusiasts. To this day, it is the ONLY website I would ever consider giving actual money to, and I am a part of a lot of other great forums.
