Your edits to a.o. catalysis
Hi, thanks for your contributions, but I have reverted your addition to Catalysis. The link you add may very well contain good info, but we are foremost trying to write an encyclopedia here, not a directory. Could you try and dig some information from the articles, and use it as a reference (see also the footnotes guideline and the reliable sources guideline). Your edits do a bit suggest that you are involved in the site (but I may be wrong), if so, could you also review our conflict of interest guideline)? Thanks!  --Dirk Beetstra T  C 15:54, 7 March 2008 (UTC)
