Our website ([login to view URL]) allows you to choose Squirrelmail or Roundcube.
There appears to be a single form, but actually there are two forms, one is hidden by javascript (if it is turned on).
I would rather have a single form with Squirrelmail / Roundcube passed as an option within the form - I believe a curl script is required to make this work.
You may need to make modifications to the Squirrelmail / Roundcube login php files, I really don't know.. (I can't make it work..)
## Deliverables
You can not develop on my server.
I am happy to upload files for you if you need to test your work.
