As has been extensively covered elsewhere, real-world money trading (RMT) will no longer be allowed for Wurm stuff from 1st March 2020. See the announcement here for full details:
This means that all sales in the various market sub-forums (WTS, auctions, etc) can no longer ask for or offer Euros, USD, etc. If you have a sales, buying or auction (or similar) thread running, please edit it to remove any RMT BEFORE 1st March 2020. Any threads still offering or soliciting RMT after this date may be locked or removed.
