I have "solved" the issue that you might not have a lot of people experiencing "yet".
but here is the deal.
I have my home computer and my lap, and I have other people with their computers working on same projects.
Right now there is no "coolaboration" way to this other than exporting the sites and sending them somehow.... which makes it a nightmare with version control, etc...
Here is the solution, I hope you implement it, it is the smartest thing I could come up with without having to develop something too extreme.
Just when publishing a site EXPORT THE XSE of the site to the site itself (this can be an option that the user can select to have done or not).
Then add the option of connecting to a site and testing PRIOR to creating the site.... is xsitepro sees the XSE file in the server then it will automatically pull it and import it (again, giving an option to the user telling him that there is a version with the date so and so and if he wants to import it and the changes, you could even put the name of the computer ((assigned by the user)) or the user that made that version) so xsitepro would import the site automatically and thus eliminate the problem of versions and working with different computers, no matter which computer you use, or which member of the team updates the site... everyone would be working on the latest version and not on a prior version that might be on the computer.
I hope you implement this, it would so much help me (and others) to make changes to websites on the go, and know that I am not destroying any other work that someone else might have done.
This is VERY IMPORTANT because even if a site is made... there is so much work that can go into it SEO-wise after the fact.
I hope that you go ahead with this and if you do please let me know....
It would speed up my work 1000 fold.
