I noticed two tournaments, one over the last weekend, one this week Mon - Sun.
There hasn't been / I haven't seen any announcement about a regular occurrence.
The links have been posted several times by piztaker and myself. It's no use to repeat them because they / their first round are over.
If you didn't receive any mail last week, contact WGT to solve the matter.
For the next tourney to come by chance, be sure to keep your eyes open. Read the ads, read in the forum, ask WGT by mail. IMO they are still figuring out if to end their hiding policy.
Practice round? Did you get a tournament link?
