I did understand your point, and MY point is that had he read the thread, he would have replied with "np, feel free to contact me if you have any further questions" or something like that, which is common for helpful people to do.
Therefore I don't believe he read your reply.
And in the event of him HAVING read the reply and didnt bother to reply with above, he wouldnt care if you sent him a PM either.

Revan,

I again see your point and I've made mine. Let's just agree to disagree somewhat, of course, not totally since I understand from both sides.

I've been on many forums and have helped many people and v.v. and oops, I guess I forgot to add to each of them 'feel free to contact me'. Somehow, I don't remember any replies that said that to me, either as I've always taken it to be implied as warranted. I'm fine with it this way (requires less typing, too).

If I find you have something I may be able to assist you with, which I don't mind, let me tell you in advance, if I don't say 'feel free to contact me', it's "implied..."

Take care.
