[xwiki-users] Markup help

Hi, At present I'm a total noob when it comes to xwiki so please forgive anything that demonstrates that in the following request for guidance/support... I'd like to create a xwiki page that, in appearance, is not dissimilar to this page: http://www.xwiki.com/xwiki/bin/view/BlogFr/ Where the difference will ocur is that I'd like to aggregate several *external* blog feeds into the main body content as per the blog post item list in the example above and the same (i.e. aggregate external feeds) for the twitter module sitting in the right column further down although ideally i'd like to mash twitter and identica feeds into a single list thus merging the timelines - and for extra kudos a de-dupe would be sweet to cut out those cross-posts and retweets. Would be cool to do the cloud as well though I suspect I'll need to try and cache an aggregated 'lookup' before attempting that feat. Finally, I'm currently working under a particular constraint - the version of xwiki I'm using is v1.5.2.12758. Any pointers re: best practice for a) embedding javascript in the page as per the twitter object and b) blog post aggregation and ideally c) some demo markup anyone could share and would be totally delighted if d) anyone wants to tell me how they'd do or have done the tag cloud from an aggregated feed. Kind Regards, Ed. PS. I've looked at this example with Groovy though I'd appreciate confirmation I can do it in the version I'm using before attempting, failing and resorting to losing head on hair from ignorant frustration ;-) i.e. any extra dependencies to do the groovy thing or can I just do this straight away with the version I currently use: http://bit.ly/8KcgLD
