One thing that might generate some interest could be an organized overtink party, only more than just an overtink session. Maybe you could combine it with an alchy/ cook/ fletch/ tink/ salvage/ imbue/ swap/ trade/ garage sale kind of thing. Maybe you could advertise it server wide (but maybe with LDers getting first-in-line privileges for the overtinking?) like a month in advance. Have it on something like an early afternoon on a Sunday or a Saturday so that it is the most likely time and day for all timezones to be reasonably able to attend.
If you could line up the overtink sessions and schedule appropriately (not sure how much interest or how many characters could provide services), then you could set aside an hour or so before that for high level trade characters to provide free tinking/salvaging/etc services in order to get all but the last tinks out of the way.
You could also have, in conjunction with the overtinking fandango, our typical raffle event, for which I'll gladly donate some stuff.
What might be kind of nice with this, if you think it has merit, would be if we advertised server-wide, for people to bring their salvage-for-trade or weapons-to-imbue and people could set up down the hill and try to get whatever bags they needed prior to the overtink sessions starting. We could get a mini-Qalabar from the old days going, at least maybe for a little while, maybe once a month or once a quarter.
There, I tossed out an idea.
Quick, someone had better toss out another one or two, or else they might be forced to go with this one.
You are all in for it now..
