is there any difference to forum if Ignorelist is empty or full of members, I mean does it have any effect on browsing speed, lags, opening pages, etc?
I haven't noticed any difference. But, if the list gets too large, you'll get a timeout when trying to view
Ignore user options. I just checked: I have 340 users on my list, and it takes a while to load already.
I expected a much longer list.
