I found the following statistics interesting. 57% of registered TFP forum users have no posts and are not TFP supporters (i.e. have not paid, though this does not count any who donate amounts less than full TFP Lifetime). Perhaps they are registering so that they can identify new posts since their last visit, but are just getting useful information without the need for interaction. About 35% have posted, but are not TFP supporters (have not paid). About 7% are TFP supporters (paid members) and nearly 90% of these have posted.
