I joined this site and haven't posted any images so i thought i'd post two pictures off my flickr. They dont really look like macros, but the flowers are very small infact.
This one was unfortunately took at ISO1600 by accident, so please be kind. 
A more recent one, i know i should have used a smaller aperture
im actually using the 350d kit lens and a +4 close up filter and handheld. it works ok but if my "macros" get any better i may upgrade to a sigma macro lens of some sort and some extension tubes.
The second one is really great
