YssGhoul is a simple addon that reminds you to summon your Ghoul
The reminder will be sent out via LibSink so all major SCT style addons should be supported. Also a reminder sound will be played to aid with the reminder. Addon supports LibSharedMedia so you should have lots of options here as long as you have other addons providing you with sounds.
the reminder can be set to remind you at intervals of .5 to 30 seconds.
