Might I make a suggestion? Put anything a year or 2 old into "mothballs". I'm talking the messages on the forum. It can still be read but not by scrolling back back or by using search.. unless.. see next paragraph.). This will do 2 things: cut down on people commenting on older messages and maybe give you a little more "room" for all the new messages that will be added over time.
Older stuff could be found under a link to archives etc. Which could be searchable. But not as easily as it is now. And maybe not set to allow trawl bots to peg it? Which might save a little on bandwidth.
(And, maybe people won't be too quick to say "the consensus of this forum on that topic is...". Because this is an ever changing forum. Regulars go away, new comers want to put their 2C in. Fresh input might give new insight yadda yadda. And there might be less "but you said 6 years ago the opposite of the advice you are sharing now." Because people grow and change their minds.)
I appreciate the heads up.. while wondering what I will read in the wee hours
