Not sure what other people think about this. Personally, I feel that the Poste needs to be where the most people in the RP community are likely to see it - ie on a board or site they visit anyway, rather than in a separate location (because let's face it, we all only have so many sites we visit every day, and are more likely to read items that are somewhere on the site we're already on than bookmark another link and visit that separately).
In the past, that central hub has always been here, hence the Poste was here. Now that these boards have lost their "CoRE" affiliation, that should be even more so; in any case the Poste has long reported on RP from right across the community so no change there.
My gut feeling would be to keep it here and potentially repost it on
UO Forums if those do see long term heavy use from the RP community, rather than go to a completely separate blog site. End of the day, layout and skins are just eye candy, personally I think being in a central location is more important.
Just one person's opinion, mind you - would be interested to hear other people's feedback.
