The changes are in large part happening because for the last 6 years or so, there has ( a ) been a sharp decline of use of individual sections of LF, and ( b ) a fairly regular crop of threads complaining that LF is dying. One of the reasons for this sense of emptiness has been the sheer number of forums for different games, each of which has a general forum, a modding forum, a debate forum, etc., each with perhaps only 2-3 members using them (or slightly more, in the case of Ahto, but still not a huge number).
It was largely redundant, and with the role of forums like LF as places for specific games has largely died off in favour of platforms like reddit, and with the death of LA, the time was ripe to close down redundant sections and concentrate the remaining member base in a place where they can and hopefully will actually interact with one another.
When it comes to nothing being explained, the explanation is right there on page one of this thread - a thread you yourself have posted in. This has been floated before as an idea a couple of times, and that thread dates to well before this process began giving an outline of what was planned. To be frank, it seems to me that if you had objections that was the time to make them known, not now that the process has already been started.
If you don't know who Lynk is, he's been around for long enough at LF, and has been fairly active in Ahto since at least 2010. I don't know how you can have missed him, really. From what I recall he was involved in introducing badges and setting up the TOR subsite.
I'm sorry, I don't get the issue here.
Oh, and speaking as another person who arrived on LF in the mid 2000s, we really aren't long-term users. There are people there who have been members since 1999. We're latecomers to the party by a long chalk, IMO.
