I'm Salleman at Wikipedia too. I'm working a bit on the Swedish WikiBook here. Some days my English is rather nuanced and witty; other days it has gone hiding under the sofa with all the dust bunnies, where I do not dare to try recollecting it.

Moreover, a cow is probably more skilled in explaining grammar than I am. But I'll write many examples instead. Hopefully, people will ask when they don't see the picture.
