Supernatural to premiere Scooby-Doo crossover at PaleyFest
Anyone attending PaleyFest will be so lucky to get a first look at this episode!
Misha Collins announced that the 2017 GISHWHES would be the last. Now the GISHWHES store is having a clearance sale.  This will only be for a few days, so if you snooze, you loose. Head on over to the GISHWHES shop for deals. Thanks to Nerds and Beyond for the notice.
In other fund raising Kim Rhodes will be raising money for proper toilets in Nicaragua through her storytime feature. Nerds and Beyond reports.
The story time will be held on Kim’s Facebook page at 8:00 p.m PST tonight, February 20th, but people are encouraged to donate early. The Supernatural family is known for coming out in droves to support charitable causes such as is and I have no doubts they’ll turn up again this time. While most of us sometimes take the access to toilets for granted, we can all imagine what it must be like to not have that available. 
Kim explained in her Facebook.
