Question regarding modified pages

[technoteen]

i am using zimbra oss

i have copied the tomcat/webapps/zimbra/h/login page and modified it to create a new page with a drop-down list of domains adjacent to the username box for login purpose
i have also inserted another logo on the page keeping the zimbra logo intact
i have kept the original page as well in my zimbra installation
i will be redirecting users by default to the new page i have created

my question is,
can i still use the zimbra collabration logo or i have to use the zimbra inside logo??

i have read the license but really cant make out what i should do

i would love to use the zimbra default logo if i can

/edit: i have just re-read the license on the website, it seems it has changed since last when i had read it, it has become even more complex now for me to understand
pls answer this question as well:
can i use the smaller zimbra powered logo only on the new page i have created instead of the the zimbra logo keeping the zimbra logo on the original page?

Well, in the open source version, you may not remove any logos.
As long as you keep our logo visible with all of the copyright notices, and the wiki/forums link (5.0 only), then you're good to go.

You may not replace the Zimbra logo with the Zimbra Powered logo. You can only add to the current logo in a separate image file (ie you can't edit the jpg file and change the zimbra logo).
