I know it's a bit off topic...
Cat, Slovene re-enactment started only 12 years ago. Although we have hundreds of castles (or ruins of them), our first medieval event happened on June 24. 1995. Since then medieval groups are on the increase, almost every town with medieval history has now it's medieval show or fair or something... But we're still all beginners, and there's no money in it - we're all "amateurs". But it has improved vastly in last few years, some of us are even being accused of living history. Which we deny, of course.
First Slovene medieval re-enactment, castle Sneznik in 1995.
Even we now have several dozen events, there isn't single event that is narrowed down to some medieval period, they're all "general middle ages", which includes mail clad spangenhelm wearing high middle ages to renaissance pretty dresses of various dance groups and musicians. Luckily nobody does Romans and Vikings. Although you can always see some rune inscribed horns and tankards, and Thor's hammers around.
And funny about that "Tolkein" stuff - gallery you visited is actually a gallery of Slovene Tolkien Society Gil-galad, and many of the re-enactors on pictures are also big Tolkien fans. I guess it shows on their costumes, it's actually the same costume they're going to wear in two week's time on our Big Annual Meeting (BAM).

Did someone mention big hats? Well, mine is certainly biggest!
