The Gypsies do progression raids from Tuesday through Friday, 7pm to 10pm server time. During these raid slots, 25-player progression content will be posted (along with some useful farm content, like the weekly raid or possibly Baradin's Hold) on some of those nights, with the remainder of the nights used for several 10-player progression raids. If you sign up for these raids, be online and ready to raid at least 15 minutes prior to the scheduled raid start time, and be prepared to raid until the scheduled end time.
Outside of these hours, there may be a number of other 10-player raids scheduled, for progression, non-progression, and possibly achievement content. Anyone with the ability to do so is welcome to post raids outside our standard raid hours at any time, but are asked to refrain from posting raids during our stated raid hours until after the 25-player raids themselves have been posted for the week.
If you sign up for the 25-player raids, please refrain from getting yourself saved to Baradin's Hold until Friday of that raid week, as we may take the raid there depending on availability of the raid itself. If we have not gone there by Friday, then you're free to pug it before the next raid week starts.
