Glogs Due

Today, Glogs are due. About five of my 22 students have been having a very hard time saving. I spoke to a Glogster representative last week, and they assured me that the problem was fixed, however, these five students have continued to lose all of the new work that they add to their Glogs. I may have to extend the deadline for these students. I wonder why Glogster continues to affect these five Glogs only.
