I use the CATEGORIES field in my contacts. ZOHO Mail supports them. You can create CATEGORIES in ZOHO mail and slide a contact into as many categories as you like. I love it!
So far so good.
But when you import contacts, ZOHO assigns the contact to only one (the first) category, and skips the rest. Thus, if you have a contact like this:
BEGIN:VCARD
VERSION:3.0
FN:Aaron Aaronsky
N:Aaronsky;Aaron;;;
EMAIL;TYPE=pref,internet:
aaaa@aol.comTEL;TYPE=work:617-555-1212
CATEGORIES:Group1,Group2,Group3,Group4
END:VCARD
Poor old Aaron is assigned to only Group1.
I don't know if this is a feature or a bug but it would be desirable to assign him to Group2, 3, and 4 as well.
