Just picking up on this one, having to wait between searches is far less annoying than having to wait for
every forum page to load because everyone is searching
The limits are put in because the forum does not run on a dedicated server and available resources have to be shared around everyone who is browsing, so while I'd prefer everyone to be able to search repeatedly, these limits can't be removed.
I will have a look over the current settings to see if I can weight things in favour of members, ie. reduce the throttle time for logged in members and maybe offset this by increasing it for guests.
