[quote=Drakel]Is there really a major difference between the two? Why/Why not? [/quote]

Not particularly, in either event, it's taking the RP over. Either before it started or after. 

[quote=Drakel]What are your Opinions on these examples?[/quote]

Doesn't bother me. If I start something and life takes me away, either before I've started it, or after, then I'd be glad if someone took it over. What am I gonna do? Have a hissyfit because they liked it enough to continue without me?

[quote=Drakel]Should either of these Be allowed in the Guild? Why/Why not?[/quote]

Yes. There is really nothing wrong with it, unless you own a copyright to the RP.

[quote=Drakel]If you were GMing would you be cool with either of these happening to your RP? Why/Why Not?[/quote]

Yep. I've given up a Bleach RP because I couldn't do it anymore.

[quote=Drakel]Would you be cool if other members did this to RPs that are NOT yours (but you are in)? Why/Why Not?[/quote]

Yeah. If I joined the RP because I liked it, it likely doesn't matter the GM - unless it's someone I've had problems with before.
