Hmm,
As Tony pointed out, we don't allow script tags in tiddler content, because of security reasons.
I did have a little look at the code. The first link seems to be a form, which should be opened in an iframe window. The second link contains some code, that initializes the hidden window.
The first script-tag contains some configuration data, which is used in the second script tag. ...
I did test the form, and it seems you don't need to be logged in, or something similar. ... Do you have a problem with spam? ..
Since google groups is public imo
you should edit your first post link to something like this:
"https://xxxxx.freedcamp.com/yyyyy/bugtracker/bugtracker_public"Otherwise everyone can see the link to your form, which could be spammed in the future.
I think we can rebuild the behaviour with TW. It's possible to dynamically open the form in a new window.
Do you want to submit bugs to different bug-trackers, or is it the same tracker for all your tiddlywiki wikis?
have fun!
