List of holiday websites

Hi

I create couple of holiday websites for example:

wdzydzekiszewskie.agro.pl
ocypel.agro.pl
etc.

where users can rent a house, room for a holiday. On the other hand there are users who can add their offer (which is listed here http://wdzydzekiszewskie.agro.pl/domy-wczasowe.html and have its own subpage for example here http://wdzydzekiszewskie.agro.pl/gospodarstwo-agroturystyczne.html)

Now I’d like to give an opportunity for users to change their offer through the website. That means they have to register, sign in, add their offer and if they wish, they can change it. I’m not an experienced user in modx and don’t know if it is possible in this cms. If yes please show me the way how it suppouse to be done, what snippets should be used.

Thanks
Pawel

I would also Like to know if Modx is suitable for designing a site that requires this type of functionality? I don’t need telling how to do it as I can learn that myself, I just need to know if its possible before I jump on the Modx wagon only to find its not gonna take me where I want to go so to speak.
