I'm using Opera. I especially enjoy the ability to create a new search shortcut simply by right-clicking in an existing search box.Some things annoy me about Opera, though. It's always tiresome to come across pages that won't display properly (especially pdf files, which for some odd reason will display ascii text the first time I load some pdfs, but works fine after refreshing the page), or at all, because you're not using IE or Firefox. I understand that this is (most of the time) not an issue because of Opera itself, but rather due to bad webpage coding (or coding just for IE/ff), but it still bugs me.

I hate WYSIWYG editors, too. One look at the source code makes me cringe.I use NotepadEx. It uses tabs, which helps me organise my pages better than Notepad, but that's about it's best feature. I like it anyway.I couldn't even get used to syntax highlighting at first. Now I kinda like it (helps me remember to close list tags, and paragraph tags - occasionally I still forget), but still don't use an editor that has it.

I wasn't aware of this. Cheers. I used to use e107 and was happy with it. I'm not the best programmer in the world so I wanted something easy to use, and it fit the bill there. Never had too many bugs anyway - just a few related to adding new emoticons to the forum. And I was happy with the skins that came with it, though some of the user-developed ones were bloody hideous. It was reasonably easy to make new skins, too, even for the forum - was just trying to get the colour scheme right before the great hard drive crash of '06 meant that I lost my test pages. Dang. I've only seen one other site that used e107 but it looked great and worked fine - and it incorporated lots of things - forum, chatbox, booking system, articles of various types.

If I had to give short answers for each, I'd say: It's a means of separating mixtures and a way to roughly identify the components of a mixture. It does this by passing the mixture along a column - each component will move at a particular rate (depending on one or more of a number of properties, like polarity and size). As above - separation (purification) and identification. Affinity chromatography uses the fact that some component of your mixture will bind to a particular part of your column, whilst others won't. For example, the chromatography column may have an antibody anchored onto it, and a certain antigen will be retained on the column whilst the rest of your mixture isn't, because nothing else will bind to it. There's heaps of other partnerships too: enzyme/substrate, metal ion/ligand... Yes - and as a rule of thumb purification is easiest if the components of your mixture are significantly different from one another. Most basic: you need a column with a stationary phase which is the material which separates your mixture, and a mobile phase - the solvent (liquid) which moves your mixture along (also involved in separation). This kind of basic idea is used in paper chromatography (a link was posted in an above post). More difficult and more specific kinds of chromatography can be a bit more complicated, or a LOT more complicated. Hope that makes some kind of sense.

Indeed. But it's all the other nanowhatsits that come with it that scare me. Like the carbon nanocars... Nanocars Fullerene four-wheelers I don't really have high hopes that these sorts of things will revolutionise ANYTHING.
