Question: I created a wordpress blog (http://raptor.hk), but i am unable to set the right sidebar into correct position. i think i have missed something in CSS. the DIV is named "rightbar". I would like the DIV to be positioned right next to the content, within the white wrapper. Also, support of fluid layout (not moving on browser resize) is needed.

the problem is solved (see my answer), but anybody can give better solutions?

Answer: 
You can use the [Users API](http://code.google.com/appengine/docs/python/users/) to authenticate users - either using Google accounts, or OpenID. If you want sessions without user login, there are a number of libraries, such as [gaesessions](https://github.com/dound/gae-sessions).
Yes, this is for me the easiest way using Python 2.7.

```
import Cookie
value_session = "userid (encrypted);time of login"
name_cookie = "sessioncookie"
expires = 2629743 # 1 month in seconds

D = Cookie.SimpleCookie()
D["name_cookie"] = value_session
D["name_cookie"]["path"] = "/"
D["name_cookie"]["expires"] = expires
print(D)

```
