| 16 | I am anxious to hear about your experiences using Calc. Send mail to |
| 17 | "jay.p.belanger@gmail.com". A bug report is most useful if you include the |
| 18 | exact input and output that occurred, any modes in effect (such as the |
| 19 | current precision), and so on. If you find Calc is difficult to operate |
| 20 | in any way, or if you have other suggestions, don't hesitate to let me |
| 21 | know. If you find errors (including simple typos) in the manual, let me |
| 22 | know. Even if you find no bugs at all I would love to hear your opinions. |
