Summary

what are the restrictions on branding!?!

Content

Hiya,

Going round the houses a bit re branding possiblities on Transitions. What we have at the moment doesnt look great - looks more like a career page - but I cant seem to get a definitive answer on what we can and cant do re the branding limitations on the portal.

Has anyone any experience on what is possible or not at all?

Thanks

Charley
