I don't know why the moderators deleted my reply.
One of the deleted posts stated:
Thank you for the response. All this links can father my knowledge .
The other stated on a different thread:
Thank your for the information it really helps me a lot.
Normally, although you may really want to thank someone by posts such as the above, these posts (and a few more I’ve seen) are likely to be reported and deleted for “low value content” or such. What that means is that they really do no add anything to the drift of the conversation of the thread, at least as far as the forum is concerned.
