Thanks Gary, but I don't want to change the subsite template nor the theme. The package is part of dotLRN and it will be one more package in the community.
I would like to use the theme with tabs (or selva or kelp or another one), but only when the forums (or assessment or another package) is called from my package (inside an iframe) I wan it to use my own template and not the default master one.
TIA
