Small suggestion.
Allow people to exit out of a window transition (exit only) out of many of the various buildings, fortresses and so forth with lockable doors. Sometimes people lock these or they default to locked (After being left unlocked) and people set their spawn points inside them. The next time they login they are trapped inside. Sometimes by no fault of their own by not even knowing the building defaults to locked or because another character with a paranoid streak locks all doors behind themselves.
I've seen this primarily around Lower areas.
I know one certain example where it has been made that you can bash one of the doors until it unlocks temporarily. That sounds like an easy enough solution.
Edit: (If desired, I know some places are meant as cool little hideouts etc, which I imagine you would need to be proficient with OL to use)
