Is the facility to create a new personal online tree working in RM8?

However small a group I choose it tells me its too big to publish an additional personal online tree.

I have eventually worked out that is probably because my existing website tree is 164MB and the limit is 200MB, according to the Wiki.

My existing tree website from RM7 is still working and I am able to make changes on the site itself. But have avoided attempting to update the data in case I lose the existing web tree.

Can anyone reassure me the facility is working before I either try to update the data in it or delete and replace?

Also does anyone think there is a way to host them on my own website so I can allow more space?
