Personally I wouldn't be prepared to give anything at this time, until it was assured that it would be going to this specific forum, and for what the money went to in lines of contribution.
To me it seems pretty clear that part of his motivation of running the Lindon Networks, whether it is a full time job, or he does this as a sideline, I am not aware of and really don't want to know. I think it would be highly unlikely that he would comment on it, because it would be very easy to appear as if he would want this for financial reasons from a negative perspective.
It would also in my opinion open up a side of things which he may wish to keep private such how the money would be used to further the forum and also if it becomes a financial venture, in that the members are effectively paying for access to the board, whether you choose to use the words donation or not, specially if that led to other benefits, or different services being available to the contributors.
Personally I have only messaged David twice, and on both times, it appears that he has not bothered to read them or reply to them, this has been seen by the lack of message receipt.
This forum has only declined because of all the bitching and infighting, the constant demands for upgrades, changes or privilages, such avatars, custom sigs, custom titles etc (to name a few) when requests have been made, then they been met with a limited response in a public forum and only the moderators can comment on what has been discussed in the staff lounge.
In my opinion there has never been a final response from David on some of those subjects, and as the sole administrator there is some subjects that the moderators cannot comment on, especially as sometimes it seems to be they are in the dark as the members.
I feel that this has led to a feel that the forum has been neglected, and it does have a large user base, who occupy the different sections, and the majority have a positive influence on the forum as a whole, despite the attempts of a few to ruin it, with their multiple names, stirring and spamming and whatever.
I would like to see CF survive and I am sure the majority would agree with that, but I also feel that there needs to be some things that change around here.
