How am I going to remember those -て and -た forms? And so on

A couple of new tools for keeping track of -て and -た forms.  [Edit:  and other verb forms.  See below.]  (Recall that if you know one, you know the other:  change the final E to an A, or the reverse.)

て-Form Practice (and more)  is a web page that asks you to enter the -て form based on the dictionary form.  It also (per my suggestion) gives you the English meaning of the word.  I'm going to do this till I ace them every time.

One of the respondents on the reddit thread where this was posted said he'd learned this mnemonic from his teacher, to get all the -て forms:

む, ぶ, ぬ->んで、う, つ, る->って、 く->いて、ぐ->いで、 す->して

are the five step verbs!

...to the tune of "Silver Bells."

Use whichever you find less annoying!

Edit:  the creator of  て-Form Practice ahead decided to do some more conjugation forms, with more to come.  The link above is so altered.
