I think what may be happening:
"people" don't exactly know what you do, and you more often than not come to a topic,
like 5 days late --perhaps that affects the perception of the valuable information you purportedly provide (and which I must admit I often skip-over, due to the delay)
... as for the access, just like with other people : "if ya don wan it, dont read it!". This is LITERALLY the
better solution / to have a separate forum -- if you
cannot ignore people who start threads, in your own section.
PS BTW: here's an example where
not being anonymous helps
that_guy's posts to be taken more seriously...
so funny.
