	# lisää samaa - 29.7.2009
	- sivun ajax updaten jälkeen elementin sijainti tulee väärin?
	
	# lisää fiksailua - 22.7.2008
	- artisokka v2.0 alkaa olla valmis, jos tämänkin sais.

	# puukottelua - 14.6.2007
	- jos sais ton näkyy vaan kerran ja feidaa sisään

	# jatkettu - 26.10.2006
	- toimaa ie/opera/firefox \o/

	# aloitettu - 25.10.2006
	- alkujaan sekä irccigallerian peepbox sekä joku ilmainen tooltippi classi joka
	vaati elementin ja tekstin sisäänsä manuaaliseksi.
	 puukotettu prototypelle classiks.
