[Still trying to figure this out - Try this:
Create a Yahoo ID
First check with moderators to see if 
	you already have a Yahoo ID (if you have a yahoo email the yahoo ID is 
	likely the part of the email preceding @yahoo.com)
If you do not have a 
	Yahoo ID, go to http://www.yahoo.com/ and click Sign In - Sign Up (or Create 
	New Account)
Then go to the Gears symbol and Click Account Information 
	(enter your yahoo password) Click Update your Contact Information. Add an 
	email address and click verify if prompted.
Go to account settings and 
	check your Aliases.]

Yahoo In Order to Read Database, Calendar, Etc. 
If you've never signed onto yahoogroups, it's a slightly confusing process
STEP 1: First see if you already 
have a yahoo ID.  It's the yahoo name you selected when you signed up for 
teaneckshuls or another yahoogroups list.  If you signed up by the web, you 
probably have a yahoo ID.   It may be part of your email.  For 
example my email is cshulman@gmail.com   If I don't 
remember my yahoo ID, cshulman might be a good guess.  Go to http://groups.yahoo.com  
and click "Groups member? Sign In."  If you know your yahoo ID, but don't 
remember your password, click "I can't access my account� and select �I forgot 
my password."  You can also ask one of the moderators at teaneckshuls-owner@yahoogroups.com to look up whether you have a yahoo ID.  
(We can't look up your password, but can see what if any is your yahoo ID.)  
If you've determined that you don't have a yahoo ID, go to STEP 2.
STEP 2: Go to http://groups.yahoo.com to register for a Yahoo ID if you don't 
already have one.  Click "Don't have a Yahoo! ID? Sign Up". Or go to https://edit.yahoo.com/registration
STEP 3: Then go to http://groups.yahoo.com/memwiz to move all your YahooGroups lists (and 
email address(es)) to your single yahoo account. Enter your email addresses 
(e.g., cshulman@gmail.com ). Follow instructions to enter your email 
addresses. You will have to verify the email address by clicking verify and 
going to that email account to obtain a confirmation code necessary to enter on 
yahoogroups.
NOW you're ready to go to http://groups.yahoo.com and see your groups. From now on, to enter 
the yahoogroups web site, just go to http://groups.yahoo.com or http://groups.yahoo.com/mygroups and enter your yahoo ID and yahoo password. 
If your browser allows cookies, you can allow the browser to remember your ID & 
password.
(TIP # 1 FOR PROS: If it's already linked to another yahoo account, and you want 
to consolidate into one yahoo account, log on to the other yahoo account and 
de-link the email address by going to http://groups.yahoo.com/myprefs and click edit email addresses.)
(TIP # 2 FOR PROS: To do email changes at once w/ a change password add new 
email on http://groups.yahoo.com/myprefs and then change the individual groups at http://groups.yahoo.com/mygroups?edit=1 )
Hope that's helpful.
