More on math markup I saw your table at Flue gas emissions and it looks nice  That led to your discussion of Wikis less than perfect math markup  You pointed out that your PNG generated at Wikicities was more compact   than the example you provided with Wiki markup   So I played around and came up with this example    Which may not be perfect but it is alot closer to your first one  Cheers     I believe placing a message on a userpage is the only way to create the message notice  Many users do put responses directly under the message for continuity but they would still need to place a notice on the other userpage to get a quick response    The smaller font is achieved with the  beginmatrix endmatrix tags   Note braces not parens  they are hard to distinguish on my monitor This is noted in HelpFormulaFractions matrices multilines section under Small Fractions where it adds that the tag forces textstyle  I am no expert so I cant provide further guidance  Concerning the power plant article you could provide a more prominant link to your article I will demonstrate but I think the main article should remain an overview with links to subsidiary articles
