I work in Ljubljana and live in another town nearby.
As others have said, there are some bike parks fairly close, one just opened like 30 mins away by car (Krvavec[/url], also Javornik and Kranjska Gora[/url] and some others further away).
There are also quite a few hills that you can ride to from city itself or are a short car ride away. Note that laws regarding riding in nature are quite prohibitive. There are also a lot of people going to nearby hills on foot, try to avoid these routes.
There are are lot of riders around here, local forum is tabla.mtb.si, feel free to ask there for more info. I would also be glad to show you around local hills. Some group rides are organized as well (either friends – privately or by LBS), lots of possibilities.

Hmm, yes this 20% off works for me, but it is not 20%?

I have cca 300 pounds (2 items – front/rear wheel) and it gives 33 pounds off, whereas 20% is ~60. It also says voucher was applied with 20% off.

What am I missing?

Whats the code for 20% of 100?
Or maybe it doesn’t work as it says UK only 🙁

NAS is basically glorified network drive. You can achieve the same* with USB disk shared over a network.

* disclaimer as actual NAS products can have other features normal USB drive does not have

So NAS is fine, but use one with RAID mirroring (or RAID5/6).
However, note that RAID 1 and 5 protect only against one disk failure, which, using cheap SATA drives, is not that much. Problem is that rebuild takes a long time with large SATA drives, creating a large window where you can loose data.

RAID6 somehow decreases chances of this happening (protects against 2 disk failures), as does using better (not cheap SATA) drives.

For software to copy files over, there are also a number of free alternatives, if you only need to copy data on predefined schedule (for example, see Cobian Backup.

So it all depends on your budget.

HP EliteBook series is good.

SLX double spider is different than tripple.
I had the same problem with mounting SLX bash to XT.
Just file it down and put some washers between it and crank so chain does not rub (I've used old credit card, cut it up to pieces, make holes and use 2 for each bolt – perfect).

Couscous, is that OK or not

Not ok, its similar to pasta (flour).
