Hi,
I read your requirements and I feel I can do a good job on the same. I do have a few questions regarding the same though -
1. Wiki-style site (collaboratively edit documents, version history, revert changes).
-------> When you mention revert changes, how often would you want to revert changes? And how much older a version would you want to revert to?
Eg: If Version 2.0.7 is the current version, then would you just want to revert to Version 2.0.6 or do you want to be able to revert to even more previous versions?
2. Ability to Login via social accounts (using discourse plugin). login accounts should be able to update profiles (such as through buddypress). discourse wp plugin can do this.
---------> Login accounts should be able to update profiles (such as through buddypress). I couldn't understand this line clearly. Since you are using a social account login, are you also providing a feature for users to store some personal info (profile page) here on the website as well?
If yes, then I do understand this requirement.
3. Ability of admin to moderate and remove accounts.
--------> You will need to provide your server details in order to set permissions for the areas that would be open for users.
I am well versed with Wordpress plugins and themes and have a license for some premium ones as well which can be used here as well providing you with flexibility.
It would be great if I could work with you. Looking forward to a reply.
Thanks & Regards,
