Ubuntu :: Single Home Partition Access With 10.04 And 11.04 Multiple Distributions

I've set up a separate Data partition, Creating a separate home partition in Ubuntu during installation Now I wish, if I'm able too, to access this partition of Data with both my 10.04 LTS edition and the new 11.04 Edition of Ubuntu.I tried once, using the methods above, to gain access to that partition, but it just denied me access to the 11.04 installation.I edited the Fstab file in mediaubuntu 11.04etcfstab, and changed back to regain access.* Mount ubuntu 11.04 first to access it*

Am I able to configure my system, that both distributions, can access the same Data partition.If so How would I go about it.I have 2 separate login names for the 2 distributions, but I want to access the same Data partition, folders, using either one. Same programs, games, and e-mail accounts.Also how would I set up Evolution, so that both operating systems use the same e-mail database, saving me from having mail in both, and no idea of where any of it is.I've read numerous posting on this, but either they don't apply, are just too technical, or only relate to 8.04 at best.
